- Moved pillar.api.utils.{gcs,storage} to pillar.api.file_storage_backends
- Implemented GCS and local storage using abstract Bucket and Blob classes
- Removed file processing from the Blob class, and kept it in the
file_storage/__init__.py class. That way storage and processing are
kept separate.
The 'manual fixups' are:
- incorrect use of dict.items() where dict.iteritems() was meant; this
results in list(dict.items()), which I changed to dict.items().
- removal of 'from __future__ import' lines, which 2to3 changes into
empty lines; I removed the empty lines.
